XBOX Live avatar... in 1 line ;)

[jihem]

Create a card, put an image ("imgName"), a field ("fldName") and a button on it.
Edit the button script and insert the mouseUp handler code :

on mouseUp
put url("http://avatar.xboxlive.com/avatar/"& (field "fldName") & "/avatar-body.png") into image "imgName"
end mouseUp

Enjoy... If you haven't a xbl avatar in mind, try "kuroyi".
I haven't been in the place since years but it's still active.
